I am a biologically female person with diagnosed with Atypical Asperger's Syndrome (Closer to Autistic). I am 21 years old and I feel like I have my sexual life very much figured out by now, though I too was confused at that age of raging hormones and an underdeveloped neurocortex. People with Asperger's are more likely than neurotypical people to have sexually deviant interests such as being gay, lesbian, bisexual, transgender, etc. (I think because they generally have no prejudices) or being into the rather kinky side (probably due to the hyper/hyposensitivity traits). When I was young I felt that my sexuality developed later than others and was confused. I claimed to be asexual until I was maybe 15 1/2 when I realized I started finding others attractive. After flip-flopping a bit between straight and gay I proclaimed myself bisexual as I considered it a literal polar opposite of asexuality therefore a less confusing choice. I could not suppress the feelings I felt for people of either genders and I wasn't too worried about fitting in with the norm anyway. I now announce my sexual interests as fluid, which is defined as having sexual interest in people with no discrimination of gender whatsoever. I have a beautiful girlfriend who I have been in love with since I was nineteen. She is a transgendered person and is discriminated against by society. I feel like we connect on a deeper level because we both have histories of bullying and we can both support each other.
If I should have advice for you my young friend, only do anything or make any decisions that you are completely confortable with. Listen to your body, and don't care about what people think. Also, always be confident and you can get any fish in the sea. Oh, and listen to the sunscreen song.
